Abstract

Abstract

The reinforced concrete (RC) frame structure with energy-dissipative outdoor-wall cladding panels (EDCP) is a new kind of structural system, in which the U-shaped steel dampers (USDs) are used to connect the cladding panels and the frame structure. The USDs can utilize the relative slip between the panels and frame to dissipate seismic energy, and thus enhance the aseismic performance of structure. The USDs and plastic hinges of beams and columns can successively yield and dissipate seismic energy under the action of fortification and rare earthquakes through rational performance-based design, which means that the main structure can remain elastic under earthquakes and low-damage under rare earthquakes, and thus has a satisfactory resilience. An energy equilibrium-based practical seismic design procedure was proposed for such structure based on the previous study, and the procedure was used to design an 8-story RC frame structure with energy-dissipative outdoor-wall cladding panels. Moreover, nonlinear time-history analysis under the action of fortification or rare earthquakes were conducted to verify the aseismic performance of the structure. The results indicated that the structure could achieve the expected performance objectives under the action of different earthquake intensities and the proposed design procedure was reasonable and feasible.
